Benchmark: Map vs Object vs Array @adelinolsn Create v3

Script Preparation code:

var quantityOfElements = 100000000;
var array = new Array(quantityOfElements);
var quantityOfTests = 10000;

for (let i = 0; i < quantityOfElements; i++) {
    array[i] = {
        id: i
    };
}

Tests:

Map create
let map = new Map(); for (let i = 0; i < quantityOfElements; i++) { map.set(array[i].id, array[i]); }
Object create
let obj = {}; for (let i = 0; i < quantityOfElements; i++) { obj[array[i].id] = array[i]; }
